Title: The Innovations of Earl L Kelly, Jr.
Introduction
Earl L Kelly, Jr. is a notable inventor based in West Chester, OH (US). He has made significant contributions to the field of welding technology, holding a total of 4 patents. His work focuses on advanced welding techniques that enhance the durability and performance of materials.
Latest Patents
One of his latest patents involves elevated-temperature, plasma-transferred arc welding of nickel-base superalloys. This innovative method allows for the repair of articles susceptible to strain-age cracking while minimizing heat input. The process begins by heating the article to a temperature between 1650°F and 2000°F in an inert atmosphere. A damaged area is then repaired using a plasma-transferred arc welder, which vaporizes a filler metal and deposits it onto the article to create a weld overlay. This technique ensures that minimal additional heat is introduced during the welding process.
Another significant patent by Kelly is a low electric D.C., low time rate polarity reversing arc welding method. This method enables direct electric current arc welding between an electrode and a workpiece surface within a current range of about 0.5-45 amps. The polarities are reversed at a low frequency rate, allowing for anodic cleaning of the workpiece surface. This innovative approach enhances the efficiency and effectiveness of the welding process.
